Abstract

A vacuum tight enclosure is constructed from an Fe-Ni-Co alloy and is intended esp. for use with hybrid and integrated microwave circuits working in the 'L' and 'K' bands. The enclosure design employs already well established soldering techniques and does not depend on critical quantities of solder or strict temperature control. The enclosure is in the form of a shallow and roughly rectangular box. Co-axial cable entry is through the end walls of the enclosure the centre conductor (4) entering through a glass to metal seal (5). The substrate (7) carrying the circuitry is soldered under vacuum at 340 deg.C, the cover plate (12) being soldered in plate at high speed using a graphite block as one electrode such that the overall enclosure temperature remains below 340 deg.C.
